With more and more types of cars being used on the roads, the problem of dealing with scratches on car paint becomes extremely necessary. Scratches can appear due to many reasons such as light collisions, flying stones, mistakes when parking...

Scratches not only reduce the aesthetics of the car but can also affect the durability of the paint layer, leading to deeper damage if not treated promptly. Professional services for removing car scratches play a key role, providing effective solutions such as polishing, ceramic coating, protective coating...

Scratches, no matter how small, can significantly detract from the aesthetic appeal and potentially reduce the resale value of the vehicle. This comprehensive guide will help you understand the structure of car paint, how to evaluate scratches, and effective techniques for removing various types of scratches on your car.

Before diving into scratch removal techniques, it is important to understand the structure of your vehicle's paint layer:

• Clear coat (gloss paint) – The outer layer provides shine and protection
• Base coat (color paint) – Colored paint layer
• Primer layer - Helps paint adhere better to metal surfaces
• Vehicle body (metal)

According to a study by the Vietnam Automotive Service Association, 95% of small scratches only affect the clear coat layer, making them relatively easy to repair.

Evaluate scratches

Proper assessment is key to choosing the right repair method. Here's how to evaluate the severity of a scratch:

• Scratches on clear coat: Can be felt with fingernails but not stuck
• Scratches to the color coat: The nail is caught and you can see the primer or metal
• Deep scratches: Exposing bare metal

Expert tip: Use a magnifying glass for a more accurate assessment.

Clean thoroughly

Before making any repairs, make sure the affected area is thoroughly cleaned:

• Wash the entire car with neutral pH car shampoo
• Use clay to remove dirt stuck in the scratched area
• Use isopropyl alcohol to remove any remaining oil or wax

Research shows that proper cleaning can improve scratch repair success rates by up to 30%.

Techniques for treating small scratches

For light scratches that only affect the clear coat layer:

1. Method of using toothpaste

• Use white, non-gel toothpaste with fine abrasives
• Apply in circular motions with a microfiber cloth
• Rinse and repeat if necessary

Success rate: Effective for 60-70% of very small scratches

2. Specialized scratch removal product

Some popular options include:

Usage Tip: Always work on small areas and use moderate pressure.

3. Double action polisher

For larger areas or multiple scratches:

• Apply cutting compound to the polishing pad
• Work at low speed (1200-1500 rpm) in overlapping lines
• Next is smooth polishing to restore shine

Car detailers report a 90% improvement in appearance for minor scratches using this method.

Treat deeper scratches

For scratches through the paint layer:

1. Touch-up paint

• Clean and lightly sand the scratch
• Apply primer (if necessary)
• Use a smooth brush or touch-up pen to apply paint accordingly
• Apply clear coat

Tip: Test color match on an inconspicuous area first.

2. Wet sanding

For more serious scratches:

• Use sandpaper with increasing fineness (1000, 2000, 3000)
• Keep the area wet while sanding
• Next comes applying compound and polish

Warning: This technique requires skill and should be performed with caution.

Professional repair

For deep scratches or when DIY methods aren't enough:

• Body repair shops can mix paint or repaint the entire panel
• Paintless dent repair (PDR) specialists can often fix scratches associated with dents
• Vinyl decals can cover extensive scratches while protecting the original paint

Average cost for professional scratch repair: 3.500.000 - 23.000.000 VND, depending on severity and method

Precautions

To minimize future scratches:

• Apply ceramic coating or paint protection film
• Use proper car washing techniques (two bucket method, microfiber materials)
• Park away from high traffic areas

Studies show that vehicles with protective coatings have 70% fewer light scratches over a 3-year period.

Maintaining your car's appearance doesn't have to be a constant battle against scratches. By understanding the nature of the damage and applying the right techniques, you can keep your car looking like new. Remember, when in doubt, consult a professional to avoid potentially costly mistakes.

Frequently asked questions (FAQ)

1. How to distinguish between clear coat scratches and deeper scratches?

To tell the difference, use the “nail test” technique. If your nail doesn't get caught when gliding over the scratch, it's a scratch on the clear coat. If the nail gets caught or you see a different color, it's a deeper scratch. About 80% of scratches usually only affect the clear coat layer.

2. What is the difference between specialized types of scratch removal products?

Scratch removal products vary in abrasiveness and chemical composition. For example:

• Meguiar's ScratchX: Contains ultra-fine abrasives, suitable for light scratches
• 3M Scratch Remover: Special formula helps fill small scratches
• Chemical Guys VSS: Combines abrasives and polymers to remove scratches and increase shine

Effectiveness may vary depending on paint type and scratch depth.

3. How does a dual-action polisher work and what advantages does it have over hand polishing?

The Dual Action Polisher combines rotary and circular motions, helping to distribute pressure more evenly and reduce the risk of damaging the paint layer. Compared with manual polishing, this machine can:

• Increase scratch removal efficiency up to 70%
• Reduce working time by 1/3
• Ensures greater uniformity across the entire surface

4. When should we use wet sanding and what are the risks to be aware of?

Wet sanding should be used for scratches deeper than the clear coat. However, this method has risks:

• Can thin the paint layer if overdone (about 10-15 µm at a time)
• Risk of creating new scratches if not done correctly
• High skill is needed to ensure uniformity
• Should only be applied with experience or under the guidance of an expert.

5. How to choose the most suitable touch-up paint color for your car?

To choose the right touch-up paint color:

• Find your car's color code in the owner's manual or on the car door
• Use this code to purchase touch-up paint from a dealer or parts store
• Test the paint color on a private area before using
• If in doubt, consult a specialist at a dealership or car paint shop
• Color accuracy can reach 95% if the correct color code is used.

6. What is the difference between removing scratches on new and used cars?

Removing scratches on new and used cars has some differences:

• New car: The paint layer is thicker and more elastic, making it easier to handle light scratches
• Old cars: The paint layer has been oxidized and thinned, so you need to be more careful when handling

For older cars (over 5 years old), you should use less abrasive products and consider repainting if there are many scratches.

7. How to prevent scratches when parking in public places?

To prevent scratches when parking in public places:

• Use mirror covers and car door covers (80% reduction in scratches due to light collisions)
• Park in the corner away from the main entrance
• Avoid parking next to bicycles or motorbikes
• Consider using a car cover when parking for long periods of time

According to statistics, 70% of scratches occur in public parking lots, so prevention is very important.

8. How to determine the depth of a scratch accurately?

To determine the exact scratch depth:

• Use a paint thickness gauge: Measure the surrounding area and the scratched area, the difference indicates the depth
• Use a magnifying glass with 10x-20x magnification to observe the scratch structure
• Use an angled LED light to see the reflection on the scratch

These methods are up to 95% accurate in determining scratch depth.

9. How to treat scratches on plastic or chrome surfaces of the car?

For plastic surfaces:

• Use specialized plastic restorers
• For deep scratches, a heat gun can be used to gently "melt" the surface

For chrome surface:

• Use specialized metal polishing cream
• For deep scratches, consider re-chroming the chrome

Processing efficiency can reach 80-90% on plastic surfaces and 70-80% on chrome surfaces.

10. Is there any method to remove scratches without using chemicals?

There are several methods that do not use chemicals:

• Using hot steam: Effective for 30-40% of light scratches on the clear coat layer
• Polishing with a wet microfiber cloth: Can remove 20-30% of very small scratches
• Using pure coconut oil: Can improve the depth of light scratches by 10-15%.

However, these methods are often only effective on very light scratches and require more time than using specialized products.
